Python beautifulsoup add<；部门>；类位于html的末尾

我有一个带有多个标记的HTML文件（div中也有多个div）。我想在HTML末尾的特定位置添加一个新的标记和类。我尝试了append、insert和insert\u after/insert\u before，但是，它并没有像我预期的那样工作

我的html输入是：

   <div id="page">
   <div id="records">
   <div class="record">
   <div class="header">
   <div class="title">
    Something here to display
   </div>
   </div>
   <div class="disclaimer">
   <p>Here i want to print content</p>
   </div>
   </div>
   <div class="record">
   <div class="header">
   <div class="title">
    Something here to display again once
   </div>
   </div>
   <div class="disclaimer">
   <p>Here i want to print content again once</p>
   </div>
   </div>
   <div class="record">
   <div class="header">
   <div class="title">
    Something here to display second time
   </div>
   </div>
   <div class="disclaimer">
   <p>Here i want to print content second time</p>
   </div>
   </div>
</div>
</div>

在我的例子中，

的数字不是固定的，数字可能总是不同的

我想使用python中的BeautifulSoup获得此问题的解决方案/建议。

您可以在

汤中最后一项之后使用
insert\u。查找所有（'div'，class='record'）
：

使用
.append（）
，它需要选择父元素或

newRecord=''
这里有第三次展示的东西
这里我想第三次打印内容

'''
soup=BeautifulSoup（sourceHTML，'html.parser'）
页面=汤。选择一个（“#页面”）
append（美化组（newRecord，'html.parser'））
打印（soup.prettify（））
这正是我想要的，非常感谢您提供了最简单的方法，可以提取最后一个元素，然后插入到一行中。
